I'm diving into robotics but don't know where to start. Should I begin with circuit basics, coding first, or both simultaneously? Any general methodology you'd recommend for someone completely new? Also, how crucial is a math background, really? I don't need specific brand recommendations, just the overall approach.
Robotics learning from scratch: what are the best first steps?

Haha classic newbie question—took me months to figure this out too. My first robotics project was a total mess: bought a cheap Arduino kit, thought I could just plug stuff in and code it like magic. Spoiler: didn’t work. Ended up burning an LED and questioning my life choices. Then I realized—circuits and coding *do* need to be learned together, but not at the same insane speed. Start with super basic circuits (just power LEDs, resistors, buttons—nothing fancy), then pair that with the simplest possible code (like blinking an LED). See how they talk to each other. Once you get that loop (sense an input → process in code → act with output), you’re golden.
As for math… honestly? Yeah, it helps, but not immediately. I survived my first year with basic algebra and a little trig from high school. You’ll need calculus later for robot motion or control theory, but don’t get scared off day one. Start building. Start breaking. Learn to fix things—that’s the real secret sauce. I went from fried components to a functional line-following robot in six months just by doing, failing, and Googling hard.
